' Be it known that I, 'VLADIMIR P. FEDoR OFF, a subject of the Czar of Russia, resident of Meriden,` County of New Haven', and State of Coinecticut, have invented certain new an .useful Improvements in Alarm- Signa'ls, of which the following is a' specification. i

This invention relates to improvements in' alarm signals, particularly to types used as theft preventing devices, the object of the invention being to arrange an audible alarm so' that when it is displaced or tampered with as to cause notification of the same.-

A further object 'is to provide such devices in forms which maybe applied to a wide variety' of articles in such manner that if the same are disturbed an effective audible signal is given..

A still'further object is to provide such devices in forms which are small in compass and readily applied without material menge inthe article to which they are attachel. u i

The implement in the compat form shown is comprised ofa base plate 50, the ends 51 of which are extended and .formed with openi'ngs to receive screws or like securing means whereby the implement may be 'astened upon any article it is desired to protec't. Rising from the base are end plates, respectively 52 and 53, and arranged parallel with the latter is a partiton 'plate 54, forming a compartment 55 all of the several plates being rigidly Secured to the rear side plate 56, which has at the lower portion of the compartment 55 a eurved enlargement 60, a similar' enlargement 61 being forned in the'rigid front plate 62, which covers the compartment 55. The main compartment is provided with a cover 63, secured by the hinges 61, at .its lower edge to the base 50, the cover beingprovided with an actuating knob 65, for manipulation; I

Secured to the rear plate 56` at the top is a partial cover having extending edges 68, while overthe lesser compartment 55, are disposed arallel plates 69 and 70, having between 't iem a recess 72, which coperates with the edge's 68, in securing a sliding cover 73, having slide g-rooves formed in the outturnedfianged edges 71, and which will be more fully described later on.

Pa'rallelwvith the cover plate horizontal plate 75,' the same extending from end to end in the main compartment, which View of the elehas at both the lowercorners and upper left hand corner, interior lugs 77, suited to re ceive screws 78, by means'of which a removable plate 80, is secured in position. Attached to the plate 80, is a bell 81. rotatable upon the stem 82, actuated by a clock work mechanism, consisting of a spring 81, attached at its inner end to a spindle 85, having a square extending head 86. A olding `loophandle 87, is attached in such n'anneithat when extended it can be used t'or winding. the spring, the oute'r convolution ot which is engaged with a gear 88'. driviug a gear train terminating in the pind-h 89, upon whchs Secured a star wheel 00, adapted to operate the escapement anehor 91 piv- 'oted at 92, and havingan operative arm 93,

carrying the 'hammer 94, adaptedto make contact with the bell When the escapernent, is released. e i

In order to' permit sound to issue from the casing, the rear cover plate 56` is provided with a plurality of openings, similaropen'- ings 95 being also formed through the endo' a cylindrical guard 97, rigidly secured'to the exterior of the cover plate 56, the-periphery of the'guard having openings 98, fore like purpose and which prevents the en- -trance of objects which mightrender the bell ineffective.

Slidably and rotatably mounted in the upper right hand portion of the casing is a spindle 100, movable in a boss formed in' the end plate 53, the spindleextending outward` to the right, and having an Operating head 101, a notched disk 102 is Secured on the spindle and has on it a `plurality 'of characters 103, while engageable with the notches in the disk are projections 10-1,formed with a rigid extension 105, of the endplate 53. i A porton of the spindle is rotatably engaged within `a sleeve 108, having a key 109,

the sleeve being slidably engaged within a split bushing l10,.rigidly set in the partition 51, having a keyway 111, the bushing being 'Ormed with a spring finge- 112, adapted to resiliently press` against the eperiphery of the'sleeve, acting as a brake thereupon. The inner end of the spindle 100, has secured to it a head 11-1 by means ot' a pin, closely adjacent to which is a rotatable disk 115,' held' in position by the nut 116, through which passes a securing pin 117. T he edge of the disk 115, is preferably curved and completely circular'except for a recess 118, the purpose 'of which will be further on explained. p

On the inner face of the disk 115, are a plurality of indentations 120, corresponding in number and location with the characters 121, -inpressed upon' the periphery of the head 11-1 and which also agree in nunher with the' characters 103 on the slotted'disk 102.

In order to hold thedisk 115, adjusted relatively to the head 111, a plunger 122, is set in a bored opening formed through the head and impelled b v the pressurespring 'spring 133, so

Secured to the plate 80, and held in either of its a-djustable positions by 'means of the Iflat that the setting of the disk 115, may be attained in a convenient 'manner.

Secured to the sleeve 108,- at its outermost end is a collar 135, separated by a space 136, from a revolublesleeve 138, with which is formed a toothed segment 140, carrying a pin 141, which extends inwardly through an arcuate slot formed in the parti'tion 54, an engages in the open 'loop 142, of a' flat ve'rtical-spring 143, Secured at its lower end to the plate 54, immediately above the corner block 7 7, the arrangement of the spring being such that the segment is kept norma in a central vertical position.

The teeth of this segment are engageable with those of the segment 146, formed on the arcuate upper end of a pendulum lev'er 147, pivoted on the'pin 148, 'pivotally mounted in the'outer plate 53, and while attached 'to the rod 147, is a weight 150, adapted to Swing in the enlargement in the lower right hand portion of the casing. It will be understood that as the upper segment 140, is movable spect to the lower actuating segment 146, that the two segments may be engaged in difl'erent relation.

Formed with asleeve 138 is a lug 151, opposite to the center of the segment 140, and having an arm 152 bent inwardly parallel with the spindle 100. In order to prevent engagement of the segments at an undesirable moment and-also to prevent over withdrawal of. the' s'pinclle 10.0, `a slide block 155, is operatively engagedwith a pair of rcds 156, which move vertically through a guide 157, rigidly Secured to the rods by means of the screws 158, and actuated by the screw 160 having a neck 161, engageable in an opening' formed through the plates 69 and 70, above which is a flange162, and an extending knurled Operating knob 163. By rotating the knob the block 155.nay be raised or loweredas desired. Therods 156 when in a raised position engage in suitable openings formed in the cover plate 73 thereby preventing it from being opened.

-Se'curedto the front of the cover plate 73,

i is a bell shaped extension 165, engaged by the sleeve 166 whichchamber 168, having a screw threaded portion 169, engaged in the upper corner lug 77, and which s adapted to containa car-i engaged' position by tridge 170, held 'in' an pivoted on thescrew a ,protctive plate 171,

172, and provided with .an :exteniing lug it'may be raised, ex?

173 by means o'f which which' isj detonated through the opening 174, as folloivs:-^--

A transverse partition versely across the space at the upper portion of the' casing partiti'on plate 54,.

longitudinally with re encircles a metallic.

175, extends trans and is formed lwith an open-,V

ing in which is rotatably and slidably ceived, the .round plunger bar 178, for at its outer end with a recessed head and carrying a front projection 180, to make contact with and detonate the tridge Encircling theplunger 17 8 is a coied sure spring' 181, the same extending between the head 179, and theplate 175, and adapted to urge the plunger forward When it is rte-- d leased; also engaged with the head 1 79,is`a

downturned projection 182, the same extendi 75,- and engageable with a laver. i

the plug 185, and which limits the rotary motion of the sleeve when motion iscommunicated by the extending stem 189, provided with a square corrugated knob 190, the screw 187, also secures a spring detent 192, adapted to make contact in an arcuate recess formed inthe outer fiange 184, of the plug 185, the same 'pressing tensional-ly against it so as to prevent it from ja'rri-ng or shaking loose in an adjusted position.

A squared extension 194, is formed with theplug 185, adapted to pass through an opening in the upper part 'of the partition plate 54, and between the sides of the channel shaped extension 194, is a detent 195, pivoted on the pin 196, pressed normally outward by the flat spring 197, the inner end of which is rgidly engaged within 'the plug 185. i

i bar, 202, having a lug 206, in which is pivoted a dog 207,pressed normally downward by the spring 208, attached to a lever. 210, pivotedin the lugs 212, formed with the bar 202, the lever 210 having a forward extenson 214, terminating in a vertical plate-like element 215, the lower front part of which -has a beveled edge 216, adapted to contact 'with the arm 152.

Engaged upon mounted in 'the .upper right hand part of the casing, ad1acent-to the p rtition plate 'E 54; a dog 221, held normall against the partton by means'ofa fiat pressure spring a 222, the end of the 'dog being a-dapted to enter a recess in thebar. 194, and make contact with the detent 195, when the plunger 178 is drawn to oppose the spring 181, and

Secured to the perforated rear casing plate a vertical pivot 220,

tition 5-1, toward the right, there being formed on the plate 224, 'a projection 225,

:the same being contactable with the end of't'he plate 215, which is also arranged to engage with the arm 152 when in an;

operative'position. e

Formed with the slee ve 186, is a lug 230, adapted to extend through a slot formed longitudinally the plate 75, which is provvided withrecesses at its ends, the same limiting the movement of the sleeve, the lug extending through the slot and being normally in contact with theupper surface of the lever 110.

In operation, the parts being in the position shown in Fiq. 20, and it being desired to reset the devices, the bell actuating the mechanism is wound, the outer hinged cover 63, being dropped and the cover plate 73 removed, .the post 190, eX- tending upward from the sleeve 186, turned upand pushed toward the right, so far as I i it, will go, this action compresses the spring 181, and the dog 221, engagng with the detent 195, holds the plunger 178.

The plate 171 is raised a Cartridge inserted in the chamber 168 and the cover plate replaced, the post is then turned horizon- `tally, and the cover plate 73 applied, and

locked by actuating the knob 163.

The release of the pl'unger 178, is attained in two difi'erent ways, one by the actuation of the knob 101, and the other by the movement of the weight 150. As has been described, the characters 103 and 121 are in correspondence at all times, the disk 115, however, is rotatable upon the spindle 100, it being efi'ected by swinging the detent 132 into the position shown in Fig, 22, then upon rotating the knob 101, the slot 118 may be set to agree with any desired character, thus permitting the operaton of the dev ce Without actuating the alarm by one famllar with the combination, which cannot be seen from the exterior.

1` he knob 163 is turned so as to move the block'155, up and release the spindle 100,

which may now be withdrawn. The disk 102 is rotated until one of its pro ections, indicated by a predetermined character, en-

' ters between the projections 101.

acting through the segments moves the arm and allows the plate 22& to turn upon the i cover over t pivot 220, releasing the detent 195, whereuponthe plunger 178 will be pushed forward violently, strikingthe `Cartridge and freeing the bell mechanism so it is caused to operate. y I

The noise made by'the Cartridge is enhanced by the bell shaped cover 165, while the bell will ring until the spring mechanism has run down. e

Ifone unfamiliar with the combination attempts to operate the knob 101,' which pressed inwardly makes contact with the dog 207, pressing back the bar 202, thereby moving the plate 215, from'engagement with the projection 225, so as to cause the dog 221, to release its contact with the detent 195, the same effect is attained.

If however the slot 118, in the disk 115, be in position as to clear the detent 207, the knob 101 may be pressed inwardly without affecting the setting of the apparatus.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is v 1. In an alarm signal, the combination with a casing, bell mounted therein and means for actuation whereof, of means receptive of a Cartridge in said casing, a plunger adapted to detonate said Cartridge, means combined with said plunger for liberating the actuating element of said bell, means for holding said plunger in an operative position, and means for releasing said plunger upon oscillating said casing.

2. In' an alarm signal, the combination with a holl'ow casing, 'of 'a bell therein,

,means for Operating said bell, means receptive of a Cartridge formed in said casing, a plunger adapted to detonate the Cartridge, means for propelling said plunger forward, means for holding said plunger When in a retracted position, and means for releasing said plunger coincident upon manipulating said casing.

3. In an 'alarm signal, the combination with a casing havinga side opening, a cover hingedly en 'aged thereover and a slidable he top of said casing, of means for looking said slidable cover in position, aficartridge receiving means in'said casng, a plunger adapted to detonate said cartridge, means for engaging said plunger in an operative position, a slidable rod having characters mounted in said casing, means for rotating said rod, and means combined with said rod whereby said plunger is released.

In testimony whereof I have afixed my signature. v
